How to remove mantis shrimp and other pests

[s0n1c87]

I have a large piece of liverock inside my 2.7fts tank. When I use touchlight shine can see gt creature alike inside those holes. Shine to take a clearer look but they hide even deeper so can't get a clear look.

I always heard a knocking sounds coming from my tank. I suspect there is mantis shrimp inside. Remove the whole piece of rock is not possible too big alr. Is there any trap to capture them.?

I empathize with you. I had the same problem months back. I tried all sorts of ways like putting in a trap but the mantis shrimp was too smart. So in the end, bobian I had to remove all my rocks to locate the mantis shrimp and so be it coz I had the intention of re-arranging my setup. I managed to catch it and in fact it was a pretty red thing. I put it in my sump and feed it with cut up prawns. Didn't see him lately and dont know if it survived the sump environment.

Good luck : )
